Subject [jira] [Updated] (CASSANDRA-9484) Inconsistent select count
Date Tue, 26 May 2015 18:12:17 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-9484?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Philip Thompson updated CASSANDRA-9484:
---------------------------------------
      Description: 
I am running the dtest simultaneous_bootstrap_test located at https://github.com/riptano/cassandra-dtest/compare/cassandra-7069
and finding that at the final data verification step, the query {{SELECT COUNT (*) FROM keyspace1.standard1}}
alternated between correctly returning 500,000 rows and returning 500,001 rows. Running cleanup
or compaction does not affect the behavior. I have verified with sstable2json that there are
exactly 500k rows on disk between the two nodes in the cluster.

I am reproducing this on trunk currently. It is not happening on 2.1-head.
